Resume HELP!!

I will be graduating in Dec 2009! I have been trying to type up my resume to start applying for jobs but i feel i am getting no where! I think because I have been working on if for so long and continually changing it I am getting way to detailed. Does anyone have any ideas or layouts that I should follow so I don't go way over board on my resume? The layout I am following is:
Objective
Education
Clinical Experience - I have listed the facility i went to, hours i completed, what floor i was on, and also a discription of what i did during that rotation.
Skills
Employment
Certifications
Affiliations
References

I would greaty appreciate any help since the jobs out there these days are slim to none! I keep siking myself out since I can't find any jobs here in the Philadelphia/Suburb area that is avaliable to graduate nurses which means I really need to sell myself not only in person but on paper!!!

Thanks for all of your help in advance!!
